I am really sad that so many people end up hurting their voices with vocal exercises. I'm even sadder because without good vocal warmups, I don't believe a voice can be as good as it can otherwise be. It can also be more easily damaged, as vulnerable as any un-warmed muscle to strain from over-exertion.
I have three simple suggestions:
- If you don't know HOW to do vocal exercises with great form, DON'T DO THEM!
- If you can't do vocal exercises properly, at least start singing lightly, easily and gradually build up to full voice. Don't just go full bore without warming your voice up.
- If you're serious about being in your best voice or improving your ability altogether, get some vocal training and learn to do a good vocal exercise routine right!
First, do no harm!
